Do not attach the end of the positivecable to the studs or L-shaped eyeletlocated above the positive (+) terminal ofyour vehicle’s battery. High current may flowthrough and cause damage to the fuses.
Do not connect the end of the secondcable to the negative (-) terminal of thebattery to be jumped. A spark may cause anexplosion of the gases that surround thebattery.
Note:In the illustration, the bottom vehiclerepresents the booster vehicle.1. Connect the positive (+) jumper cable tothe positive (+) terminal of the dischargedbattery.
2.Connect the other end of the positive (+)cable to the positive (+) terminal of thebooster vehicle battery.
3. Connect the negative (-) cable to thenegative (-) terminal of the boostervehicle battery.
4.Make the final connection of the negative(-) cable to an exposed metal part of thestalled vehicle's engine, away from thebattery and the fuel injection system, orconnect the negative (-) cable to a groundconnection point if available.

Note:The front and rear washer systemsare supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.Only use a washer fluid that meets Fordspecifications. See Capacities andSpecifications (page 381).
State or local regulations on volatile organiccompounds may restrict the use of methanol,a common windshield washer antifreezeadditive. Washer fluids containingnon-methanol antifreeze agents should beused only if they provide cold weatherprotection without damaging the vehicle’spaint finish, wiper blades or washer system.
FUEL FILTER
Your vehicle is equipped with a lifetime fuelfilter that is integrated with the fuel tank.Regular maintenance or replacement is notneeded.
CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosivegases which can cause personal injury.Therefore, do not allow flames, sparks orlighted substances to come near the battery.When working near the battery, always shieldyour face and protect your eyes. Alwaysprovide correct ventilation.
When lifting a plastic-cased battery,excessive pressure on the end wallscould cause acid to flow through the ventcaps, resulting in personal injury and damageto the vehicle or battery. Lift the battery witha battery carrier or with your hands onopposite corners.
WARNINGS
Keep batteries out of reach of children.Batteries contain sulfuric acid. Avoidcontact with skin, eyes or clothing. Shieldyour eyes when working near the battery toprotect against possible splashing of acidsolution. In case of acid contact with skin oreyes, flush immediately with water for aminimum of 15 minutes and get promptmedical attention. If acid is swallowed, call aphysician immediately.
Battery posts, terminals and relatedaccessories contain lead and leadcompounds. Wash hands after handling.
For vehicles with Auto-Start-Stop thebattery requirement is different. Youmust replace the battery with one of exactlythe same specification.
Your vehicle is fitted with a Motorcraftmaintenance-free battery which normallydoes not require additional water.
When a battery replacement is required, youmust use a recommended replacementbattery that matches the electricalrequirements of the vehicle.

Maintenance

Note:If your vehicle has a battery cover,after cleaning or replacing the battery, makesure you reinstall it.
Note:See an authorized dealer for batteryaccess, testing, or replacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page402). Reset the power windowsbounce-back feature. See PowerWindows (page 104). Reset the radiostation presets. See Audio Unit (page402).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.
